Re: [linuxtools-dev] Valgrind UI Java Null pointer
|
Hi,
I don't know the root cause of that exception although I suspect it is
related with absence of valgrind in the environment.
Anyway, I found an opportunity to improve whichVersion() method and thus
submitted a patch for review: https://git.eclipse.org/r/10370

Subject: [linuxtools-dev] Valgrind UI Java Null pointer
Hi all,
Not sure this is the spot for this type of question, but here it goes.
I've been attempting to use Valgrind on Eclipse. However as soon as I open the UI for the profile I get an error. I've not encounter this error in any other usage within this Eclipse version.
The error on UI open : java.lang.NullPointerException
I've pasted my session log for one instance of the error at the end of this email.
My Eclipse version.
Version: 3.8.0
Build id: I20120502-2000
My computer is Ubuntu 12.10:
Linux workstation 3.5.0-22-generic #34-Ubuntu SMP Tue Jan 8 21:47:00 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
Any help on this would be greatly appreciated. Trying to track down a memory bug on my program, but Ican't use this tool.
